It is no longer necessary to prevent the clearing of the following: - Relationship::relatedElement -- This is no longer a derived union, it is just a regular derived property now implemented using a delegate. - Annotation::annotatingElement and AnnotatingElement:: annotation -- Documentation is now a kind of Comment, not a relationship that needs special handling.
- Moved special handling of ownedRelatedElements for Dependencies to post-processing in an adapter.
- These methods had invocation delegates implemented, but the "@generated NOT" tag had erroneously not been removed. - Also removed handwritten code for Feature::isOrdered which was not per spec.

Background
There is non-generated code in the
Implclasses (in packageorg.omg.sysml.impl), inserted to work around limitations in parsing using Xtext. In particular, there were previously a number of methods that were specifically commented as “Xtext workarounds”. Ideally, these would be better handled as actions taken when constructing the abstract syntax tree during parsing, but that is not supported in the Xtext grammar language. Instead, this PR implements a mechanism that makes the necessary changes after the construction of the syntax tree, but before other processing is done on it, so this code no longer needs to be inserted into theImplclasses.Note, however, that it does not replace the following mechanisms:
Feature::isNonuniqueproperty to parse thenonuniquekeyword.Expression::operandproperty to parse the KerML expression notation.It also does not remove a number other cases of handwritten code, mostly related to property default values and additional method overrides, which may be addressed in a future PR.
